Patented Nov. 1, 1932 JOSEPH OKEEFE, OF DUMONT, NEW JERSEY HANDY CHART AND PENCIL Application filed March 21, 1932. Serial No. 600,128.

This inventionrelates to a handy chart and pencll and has for an ob ect the provision of a simple, compact durable, eflicient device whereby a mechanic,a draftsman, an engineer, architect, bricklayer, mason, or the like can have on hand a little compact device containing a chart on which are disposed figures useful to him for reference in connection with his work and preferably at the same time in corporate this handy chart device with a pen or pencil and an eraser so tnat the one device possesses several useful functions.

A furtherobject is to provide a device of the character above described which is simple and economical to manufacture and easy to operate.

' Further andmore specific objects, features and advantages will more clearly appear from a consideration of the specification hereinafter taken in connection with the accompanying drawing which forms part of the inven tion and which illustrates a present preferred form of the invention.

Briefly the invention comprises a tubular element having a hollow chamber within which a chart is disposed to be wound inone direction or another past a sight opening in the tube for observation of the figures on the chart. This chart is mounted on supports rotatable through the'manipulation of suitable gearing by turning the end cap of the tube. This turnable end of the tube preferably supports an eraser. The other end of the tube or cap may or may not be provided with any well known pen or pencil construction. The device preferably may be made in sections so as to make it easy to put'together and to take apart and to manufacture.

The preferred present formof the invention is illustrated in the drawing of which:

Fig. 1 is an elevation partly in section of the device shown in pencil form;

Fig. 2 is a similar view taken at right angles to Fig. 1 showing more of the interior of the mechanism in section;

Fig. 3 is a horizontal sectiontaken on the line 33 of Fig. 1; y

Fig. dis a horizontal cross section on the line 44 of Fig. 1;

Fig. 5 is adetailedsection of the manner in which the end of the roll or chart is fastened to the supporting rod.

In the preferred form of the invention the device is embodied in the form of an elongated tube having a chamber 11 throughout most of its length. This tube has preferably integral caps 12 and 13 at its opposite ends. As shown in the drawing the tube may be formed in two elongated semi-cylindrical pieces such as 14 and 15 shown in Fig. 3. It may, however, bemade in one piece with the caps 12 and 13 removable.

At the lower end the tube is exteriorly threaded as at 16 and a pencil portion 17 having an interiorly threaded sleeve-like end 18 is screwed onto the elongated tube and is provided with the usual tapered end 19 containing the slidable lead 20 operated in any well known manner by the manipulation of a spiral slot and pin arrangement roughly 7 indicated by the numeral 21. This lead in the usual manner is fed forward and backward by turning the tapered end '19 in one direction or the other. At the other and upper endof the tube it is exteriorly threaded as at 22 and there is disposed thereover a cap 23 having an interiorly threaded sleeve 24 to be threadably screwed on the upper end of the tube. This cap 28 has a central bore 25 to receive a turnable stub shaft 26 loosely therein. The outer end of this shaft is fixed on acup shaped casing 27 and carrying an embedded eraser 28 therein. This casing 27 is turnable to turn the stub shaft 26. The other end of this stub shaft is journalled in a bore indicated by the dotted lines 29 in the cap 12. The stub shaft has thereon a gear 30 meshing on opposite sides with adjacent gears 31 and .32 which are respectively dis posed on sleeves 33 and 34. rotatably journalled in grooves 35 and 36 formed in the cap 12. These sleeves receive the upper ends respectively of rods 37 and 38 the other ends of which are j ournalled in any suitable bores, not shown, in the lower cap 13.

These rods,-one of which 37, is shown in Fig. 5 in section, are adapted to receive respective ends of a roll of material such as a chart 39. Therods are fastened to the ends of this roll or sheet of material by means of an... .4. (u

a spring or wire 40 passing through a transverse aperture 41 in the rod 37 and through holes such as 4-2 in the material and tied therearound as indicated in Fig. 5, thus fastening the respective ends of the sheet of material to the respective rods supporting it.

It will be obvious that as the cup shaped casing 27 is turned it turns the shaft 26 which turns the gear 30. The engagement of the gear 30 with gears 31 and 32 turns the sleeves 33 and 34 in opposite directions, this causes turning of the rods 37 and 38 and consequential rolling or winding of the sheet or chart 39 in one direction or the other. This sheet or chart is disposed within a hollow chamber 11 beneath a longitudinal slot or sight opening 43 in the tube which opening is filled by a glass 44. preferably of the magnifying type so that indicia marked on the chart as indicated at 45 may be readily observed. This chart may be arranged with tables or figures suitable for any particular type of work such as draftsmen, civil engineers, automobile mechanics, bricklayers, masons, carpenters and the like so that merely by turning the eraser casing on the upper end of the device the chart or table can be turned to perceive the proper figures. This operation will take place whether or not the lower end of the device is provided with a pencil. It may be provided, if desired, with a small fountain pen or other attachment.

Vhile the invention has been described in detail and with respect to a present preferred form thereof it is not to be limited'to such details and forms since many changes and modifications may be made inthe invention without departing from the spirit and scope of the invention in its broadest aspects. Hence it is desired to cover any and all forms and modifications of the invention which may come within the language or scope of any one or more of the appended claims.

What is claimed, is:

1. In a combination of the class described, a tubular body portion having a chamber, a chart receiving rod rotatably disposed therein, the end of the chart wrapped around said rod, said rod having a transverse aperture therein and an engaging wire or cord passing through the end of the chart and the transverse aperture in the rod to tie the chart to the rod.
